The paranoid and really funny guy on King of the Hill. Dale's wife Nancy cheated on him and had a kid (Joseph) with John Redcorn, who is an Indian American and Dale believes that because Joseph is so tan and dark that his great grandmother was Italian, and in one episode that "aliens" impregnated Nancy. Dale does not sign his real name on anything he signs, he uses the name Rusty Shackelford, which he also has the birth certificate of. Records all of his phone calls, has metal cage doors (like in malls) to roll down over his windows and doors. Has his fake little security company "Dale-Tec" that doesn't do anything except give you a bunch of free Dale-Tec balloons when you sign up. Also he writes his own local newspaper called "The Gribble Times" that covers news and events in the alley. Believes that the CIA and FBI are bad. Has theories and conspiracies on just about anything that happens or anything that anyone says.
